[Abstract]:With the rapid development of the wireless sensor network and the Internet of Things technology, more and more occasions need to be based on location-based services. The ZigBee technology is widely used in the wireless sensor network with its low cost, low power consumption and high reliability. Therefore, it is of great practical significance to realize the positioning of the target in the ZigBee network. In this paper, the three-dimensional positioning technology of the target in the ZigBee network is studied. Based on the research of the ZigBee technology and the wireless sensor network location technology, the positioning system based on the received signal strength indication (RSSI) is selected to design the positioning system, and the method for obtaining the parameter of the ranging model is optimized by means of means of mean filtering and linear fitting. The positioning system designed in this paper includes three parts of the ZigBee network node hardware platform, the node software and the location management computer software. Wherein the ZigBee network node hardware platform is a core of a CC2530 chip, and comprises a radio frequency module and an auxiliary function module. The node software is developed on the basis of the Z-Stack protocol stack of TI company, and the function and program flow of each type of node in the network are introduced in detail. The computer software of location management is developed in the environment of Visual C ++ 6.0, and the detailed design scheme and function of the computer software for location management are given. Finally, the positioning system designed in this paper is tested by the experiment, and the experimental results are analyzed. The results show that the system designed in this paper has the function of three-dimensional positioning of the target. At the same time, the next research direction is pointed out for the deficiency of the system.
